Hi, I wanted to try the "minimal runtime" option of ubsan because it might be faster and has other benefits. See https://clang.llvm.org/docs/UndefinedBehaviorSanitizer.html#minimal-runtime
Unfortunately it seems to be available only with clang on Linux, not (yet?) gcc, so I configured --with-additional-ubsan-checks=-fsanitize-minimal-runtime --with-toolchain-type=clang but after some compilation I run into this link error : jdk/lib/server/libjvm.so: undefined symbol: __ubsan_handle_type_mismatch_minimal Any ideas what's wrong here ? https://github.com/systemd/systemd/issues/26975 suggests that we might need to adjust the linker settings to allow undefined symbols , not sure if this is the same issue ? On the other hand, I tried the minimal runtime option with some standalone program examples outside the OpenJDK, and The error output was indeed “minimal” (without line numbers of the error); so it looked not very useful to me but this might be my limited understanding. Any experience with this option ? Best regards, Matthias
